Abstract
En 中文
Deserts are hostile environments to plant life due to exposure to abiotic and poor soil quality. Desert plants have evolved to cope with these stresses, and for thousands of years humans have used these plants as sources of food, fiber, and medicine. Due to desertification, the amount of arable land is reduced every year; hence, the usage of these species as substitutes for some crops might become one of the solutions for food production and land remediation. Additionally, increasing our understanding of how these plants have adapted to their environment could aid in the generation of more resistant staple crops. In this review, we examine three desert plant species and discuss their developmental aspects, physiological adaptations, and genetic diversity and the related genomic resources available to date. We also address major environmental challenges and threats faced by these species as well as their potential use for improving food security through stimulating stress resistance in crops.
